I agree with your stirrups being too long, that being said you should be able to ride without stirrup as well as you do with, try some no stirrup work on a different horse. You also really need to get her in frame, like CandyCanes said with her back hollow like that, nobody is being helped. Like BugZapper89 mentioned you CANNOT ignore your position, rider position plays a key role in the movement of the horse.
